Abstract
AbstractThe life table and predation rate ofScolothrips longicornisPriesner fed onTetranychus urticaeKoch were examined at 26°C under laboratory conditions. The age‐stage, two‐sex life table was used to analyse the raw data in order to account for the varying developmental rates among individuals and both sexes. The intrinsic rate of increase (r), the finite rate of increase (λ), the net reproductive rate (R0), and the mean generation time (T) were 0.156 day−1, 1.168 day−1and 29.15 offspring, and 21.69 days, respectively.Scolothrips longicornisconsumed 18.40 and 24.47T. urticaeeggs during the first and second larval stages, respectively. The mean consumption rate for females and males during the longevity was 276.26 and 359.79 eggs of Two‐spotted spider mite, respectively. The net consumption rate, which considers survival, was 194.03T. urticaeeggs per individual. The transformation rate fromT. urticaepopulation to predatory thrips offspring was 8.9.
